Description

Procédé et dispositif de régulation de fa dureté de l'eau pour une  Method and device for regulating the hardness of water for a
habitation.  dwelling.
L'invention concerne un procédé et un dispositif de régulation de la dureté de l'eau pour une habitation, notamment comportant un osmoseur ou un dispositif de filtration ou un dispositif d'ultrafiltration. The invention relates to a method and a device for regulating the hardness of water for a dwelling, in particular comprising an osmosis unit or a filtration device or an ultrafiltration device.
Dans son principe, un osmoseur ou un dispositif de filtration ou un dispositif d'ultrafiltration rejette à l'égout autant d'eau, et même parfois beaucoup plus, chargée en minéraux qu'il ne produit d'eau osmosée ou filtrée ou ultrafiltrée, dénommée par la suite « eau pure ». In principle, an osmosis or filtration device or ultrafiltration device discharges into the sewer as much water, and sometimes even more, loaded with minerals that it produces osmosis water or filtered or ultrafiltered, hereinafter referred to as "pure water".
Une perte d'eau aussi importante, quand on connaît le coût de l'eau, n'est plus admissible. Such a significant loss of water, when the cost of water is known, is no longer acceptable.
Il est connu par les documents FR 2979339 et FR 2979628, qui ont pour titre ."Dispositif destiné à optimiser des purificateurs d'eau par osmose inverse sans rejet d'eau à usage domestique et permettant de supprimer la plupart des interventions de maintenance" et "Dispositif permettant le rinçage au moyen d'eau purifiée des membranes des purificateurs par osmose inverse sans rejet de rinçage, donc spécialement adapté aux osmoseurs sans rejet d'eau". It is known from documents FR 2979339 and FR 2979628, which are entitled "Device for optimizing water purifiers by reverse osmosis without discharge of water for domestic use and to eliminate most maintenance interventions" and "Device for rinsing with purified water the membranes of reverse osmosis purifiers without rinsing rejection, therefore specially adapted to reverse osmosis without water discharge".
Les inventions décrites dans les documents cités ci-dessus sont adaptées aux purificateurs par osmose inverse sans rejet d'eau à usage domestique qui ne possèdent pas de circuit de mise à l'égout. Toutefois les dispositifs décrits dans les documents français, cités ci-dessus, ne tiennent pas compte de la qualité de l'eau nécessaire aux canalisations, aux lave-vaisselles et aux machines à laver le linge, notamment en ce qui a trait au calcaire. En effet, les dispositifs décrits fournissent de « l'eau pure » qu'à un robinet, alors que le reste de la maison est alimenté en eau pouvant être chargée de calcaire. The inventions described in the documents cited above are suitable for reverse osmosis purifiers without water discharge for domestic use that do not have a sewage system. However, the devices described in the French documents, cited above, do not take into account the quality of water needed for pipes, dishwashers and washing machines, especially with regard to limestone. In fact, the devices described provide "pure water" only at a tap, while the rest of the house is supplied with water that can be loaded with limestone.
Le document WO 2015/010219 décrit un procédé et un dispositif de traitement d'une eau de ville et/ou de source dans lequel « l'eau pure » est mélangée à i l'eau qui n'est pas encore traitée d'une manière aléatoire. Cette manière de faire ne permet pas de garantir la dureté de l'eau fournie à l'habitation. The document WO 2015/010219 describes a method and a device for treating a city and / or source water in which "pure water" is mixed with i water that is not yet treated in a random way. This way of doing things does not guarantee the hardness of the water supplied to the house.
L'invention a pour buts de fournir un procédé et un dispositif de régulation de la dureté de l'eau pour une habitation, notamment comportant un osmoseur ou un dispositif de filtration ou un dispositif d'ultrafiltration, ne rejetant aucune eau lors de la filtration, mais recyclant et récupérant l'eau de rejet d'un osmoseur ou d'une ultrafiltration, tout en alimentant toute la maison en eau ne présentant qu'une faible quantité de calcaire dissous autrement dit une eau présentant une dureté comprise entre 8° et 12° français, selon les normes minimales The invention aims to provide a method and a device for regulating the hardness of water for a home, in particular comprising an osmosis unit or a filtration device or an ultrafiltration device, rejecting no water during filtration but recycling and recovering the discharge water of an osmosis or ultrafiltration, while supplying the whole house with water having only a small amount of dissolved limestone, in other words a water having a hardness of between 8 ° and 12 ° French, according to the minimum standards
conseillées par l'OMS. advised by WHO.
Ces buts sont atteints avec un procédé de régulation de la dureté de l'eau pour une habitation selon l'invention définie à la revendication 1 et avec un dispositif pour sa mise en œuvre selon l'invention définie à la revendication 3. These objects are achieved with a method of regulating the hardness of water for a dwelling according to the invention defined in claim 1 and with a device for its implementation according to the invention defined in claim 3.
L'invention sera mieux comprise et ses caractéristiques apparaîtront plus clairement à la lecture de la description de réalisations données à titre d'exemple en regard du dessin annexé dans lequel : The invention will be better understood and its characteristics will appear more clearly on reading the description of embodiments given by way of example with reference to the appended drawing in which:
La figure unique représente un schéma d'un dispositif de régulation de la dureté de l'eau pour une habitation selon l'invention. The single figure shows a diagram of a device for regulating the hardness of water for a dwelling according to the invention.
Comme on le voit sur le schéma représenté sur la figure unique, l'eau d'alimentation de l'habitation arrive par une conduite 10 et passe par un réducteur de pression 11, qui réduit la pression à 4 bars. Ensuite elle arrive sur l'appareil 12. L'appareil 12 est un bloc qui comprend trois vannes 13, 14 et 15, un clapet de sécurité et une vis de réglage 22 pour le mélange des eaux. Cet appareil peut être acheté chez « ROBINEX SA » à CH-5035 Unterenfelden, par exemple sous le nom "Interpass". Ledit appareil 12 étant modifié par l'inventeur en ce qui concerne une vanne clape 15. Sur la partie gauche sur le dessin l'appareil 12 comprend une première vanne 13, qui permet de faire entrer l'eau par un conduit 23 dans un dispositif de stockage dynamique 19. Le dispositif de stockage dynamique 19 est constitué par un tuyau souple enroulé sur lui-même en bobine. Ledit tuyau sera par exemple en tout matériau connu pour tuyau d'arrosage et aura une longueur égale ou supérieure à 10 m et un diamètre intérieur de 2 cm, qui sera adaptée à la quantité d'eau utilisée dans l'habitation. Pour 10 m nous aurons un stockage dynamique de : nr2x l = rr O.01 x 100 = 3.1416 x 0.01 x 100 = 3.1416 litres. Pour 100 m nous aurons un stockage 31.1416 litres d'«eau pure », ce qui correspond à environ 60 I d'eau utilisable d'une dureté 100 ppm (partie par million) pour une dureté initiale de 350 ppm. As seen in the diagram shown in the single figure, the supply water of the house arrives via a pipe 10 and passes through a pressure reducer 11, which reduces the pressure to 4 bar. Then it arrives on the apparatus 12. The apparatus 12 is a block which comprises three valves 13, 14 and 15, a safety valve and an adjusting screw 22 for the mixing of water. This device can be purchased from "ROBINEX SA" at CH-5035 Unterenfelden, for example under the name "Interpass". Said apparatus 12 being modified by the inventor with regard to a valve clape 15. On the left part of the drawing the apparatus 12 comprises a first valve 13, which makes it possible to bring water through a conduit 23 into a device dynamic storage 19. The dynamic storage device 19 is constituted by a flexible hose wound on itself in a coil. Said pipe will for example be of any known material for garden hose and will have a length equal to or greater than 10 m and an internal diameter of 2 cm, which will be adapted to the amount of water used in the dwelling. For 10 m we will have a dynamic storage of: nr 2 xl = rr O.01 x 100 = 3.1416 x 0.01 x 100 = 3.1416 liters. For 100 m we will have a storage 31.1416 liters of "pure water", which corresponds to about 60 I of usable water with a hardness of 100 ppm (parts per million) for an initial hardness of 350 ppm.
L'appareil 12 a dans sa partie centrale une vanne clapet 15 tarée à 1 bar de différence, vanne clapet ajoutée par l'inventeur à l'appareil "interpass" ,qui permet à « l'eau pure » de se mélanger avec l'eau d'alimentation de l'habitation de manière à présenter une dureté comprise entre 8° à 12° français et un ph stabilisé entre 6,8 et 7,4. De plus, l'appareil 12 comporte une vis de réglage 22 permettant d'obtenir la dureté désirée, et la vanne 14 commande le circuit d'entrée pour alimenter l'habitation par la conduite 17. La pression de l'eau de consommation sera contrôlée par un appareil 18 qui la maintiendra à 4 bars. L'eau arrivant par la conduite 10, passe du bloc 12 dans le dispositif de stockage dynamique 19 par le conduit 23 comme indiqué par les flèches tracées à côté des conduits sur le dessin. L'eau dans le conduit 23 reçoit du conduit 24 de « l'eau pure » avant d'être introduite dans le dispositif de stockage dynamique 19. «L'eau pure » arrivant par le conduit 24 vient d'un circuit de purification de l'eau par les conduits 5 et 21. The device 12 has in its central part a valve valve 15 calibrated at 1 bar difference valve valve added by the inventor to the device "interpass", which allows "pure water" to mix with the water supply of the house so as to have a hardness of between 8 ° to 12 ° French and a stabilized ph between 6.8 and 7.4. In addition, the apparatus 12 comprises an adjustment screw 22 making it possible to obtain the desired hardness, and the valve 14 controls the input circuit to supply the dwelling via the line 17. The pressure of the drinking water will be controlled by a device 18 which will maintain it at 4 bars. The water arriving via the pipe 10, passes from the block 12 in the dynamic storage device 19 through the conduit 23 as indicated by the arrows drawn next to the ducts in the drawing. The water in the conduit 23 receives from the conduit 24 of "pure water" before being introduced into the dynamic storage device 19. "Pure water" arriving via the conduit 24 comes from a purification circuit of the water through the ducts 5 and 21.
Le circuit de purification de l'eau comprend une pompe 9, un dispositif anti colmatage 1 , par exemple comme décrit dans le document WO 86/04887, un osmoseur 2 présentant une membrane 3 et un dispositif de filtration décantation 6. À la sortie du dispositif anti colmatage 1 l'eau est envoyée dans un osmoseur 2 présentant une membrane 3, mais pourrait aussi être envoyée dans un dispositif de filtration ou dans un dispositif d'ultrafiltration. « L'eau pure » sortant de l'osmoseur 2 ou du dispositif de filtration ou du dispositif d'ultrafiltration, est envoyée par le conduit 5 dans un conduit 21 et ensuite par le conduit 24 dans le conduit 23 pour aboutir dans le dispositif de stockage dynamique 19 en attendant d'être utilisée ou d'être réinjectée dans le circuit de purification. Le circuit de purification de l'eau étant constitué par un conduit 4 alimentée par l'eau rejetée par l'osmoseur 2, ou par un dispositif de filtration ou un dispositif d'ultrafiltration, et est injectée dans un dispositif de filtration décantation 6, que l'on trouve dans le commerce et à la portée de l'homme de métier. Puis l'eau par le conduit 8 sera mélangée à l'eau sortant du dispositif de stockage dynamique 19 par les conduits 20 et 25 dans la pompe 9. Il est prévu sur le conduit 25 un clapet anti retour 7 empêchant l'eau du circuit de purification d'entrer dans le circuit d'alimentation de l'habitation 17. Le dispositif de filtration décantation 6 sera vidé régulièrement des déchets sans perte d'eau, et lesdits déchets seront séchés et utilisés pour notamment pour faire des matériaux de construction. The water purification circuit comprises a pump 9, an anti-clogging device 1, for example as described in document WO 86/04887, an osmosis unit 2 having a membrane 3 and a settling filtration device 6. At the outlet of the anti-clogging device 1 the water is sent to an osmosis unit 2 having a membrane 3, but could also be sent to a filtration device or to an ultrafiltration device. "Pure water" leaving the osmosis unit 2 or the filtration device or the ultrafiltration device, is sent via line 5 into a conduit 21 and then through the leads 24 in the conduit 23 to end in the dynamic storage device 19 while waiting to be used or to be reinjected into the purification circuit. The water purification circuit consisting of a duct 4 fed with the water discharged by the osmosis unit 2, or by a filtration device or an ultrafiltration device, and is injected into a decantation filtration device 6, found in commerce and within the reach of the skilled person. Then the water through the conduit 8 will be mixed with the water leaving the dynamic storage device 19 through the conduits 20 and 25 in the pump 9. There is provided on the conduit 25 an anti-return valve 7 preventing water circuit purification system to enter the housing supply circuit 17. The decantation filtration device 6 will be regularly emptied of waste without loss of water, and said waste will be dried and used especially for making building materials.
L'eau circulera dans le circuit de purification aussi longtemps que la pompe 9 sera enclenchée et aucune eau ne sera rejetée à l'égout. Ce qui entraine que l'eau dans le dispositif de stockage dynamique deviendra de « l'eau pure ». Dès qu'une consommation d'eau se fera dans la maison « l'eau pure » sortira du dispositif de stockage dynamique 19 par le conduit 20 entrera dans le bloc 12 par le conduit 16 et la vanne 14, ladite « eau pure » sera mélangée à de l'eau d'alimentation par une vis de réglage 22 assurant le mélange des eaux pour une dureté comprise entre 8° à 12° français et un ph stabilisé entre 6,8 et 7,4, selon les normes en vigueur. Il est de plus prévu une vanne clapet 15, tarée à un bar de différence, dans le bloc 12, pour les cas où il y aurait une très grande consommation dans l'habitation. The water will circulate in the purification circuit as long as the pump 9 is switched on and no water will be discharged to the sewer. This causes the water in the dynamic storage device to become "pure water". As soon as a consumption of water will be made in the house "pure water" will leave the dynamic storage device 19 by the conduit 20 will enter the block 12 through the conduit 16 and the valve 14, said "pure water" will be mixed with feed water by a setting screw 22 ensuring the mixing of water for a hardness of between 8 ° to 12 ° French and a ph stabilized between 6.8 and 7.4, according to the standards in force. There is further provided a valve valve 15, calibrated at a difference bar, in the block 12, for cases where there would be a large consumption in the home.
Comme on peut le constater on dispose d'un dispositif simple, donc bon marché, ne rejetant aucune eau à l'égout et permettant de régler de manière très précise la dureté de l'eau. Le dispositif selon l'invention permet d'alimenter une habitation en eau conforme aux normes actuelles. As can be seen we have a simple device, so cheap, not rejecting any water in the sewer and to adjust very accurately the hardness of the water. The device according to the invention makes it possible to supply a house with water in accordance with current standards.
